2 Claims. (01. 214-421) This invention relates to bobbin carriers.

rier for bobbins wherein the bobbins may be transported from one machine to another and dumped from a basketor box into a bobbinbin.

Another object of this invention isto provide a-carrier which includes a dumping cradle desig d to receive a basket or box containing bobbins, the cradle being tiltablein a portable frame and including means forlocking the basket or box therein.

H A further object of this invention is to provide an improved means for rockably mounting a cradle in a portable frame so that the cradle may be shifted laterally of the frame during the tilting operation in order to assure discharge of the bobbins in the bin. The mounting means also includes means whereby the discharge side of the cradle is locked against downward and rearward movement until the cradle is disposed insubstantially upright position. With the above and other objects in view, my invention consists in. the arrangement, combination and details of construction disclosed in the drawing and specification, and then morepar- .ticularly pointed out in the appended claims.

Figure 11 is a fragmentary sectional view taken on the line I l| l of Figure 10,

Figure 12 is a fragmentary end elevation, partly insection, of the upper portion of the mobile frame.

5 Referring to the drawings, the numeral I 5 designates generally a mobile frame which includes a lower rectangular frame it; having end castor wheels I! mounted thereon, and intermediate wheels I8. The frame It; has secured to the rear thereof a pair of upright angle-shaped frame members I9 and a pair of U-shaped channel 7 ing position.

The channel members 23 comprise guides for the cradle to be hereinafter described, and upper angle frame members 2| extend vertically upwardl from the guides 20 and are connected to the rear uprights [9 by upper end angle members 22. The end members [9 are connected together by an upper horizontal connecting bar 23 and the front angle members 2| "are connected together by an angle-shaped connecting bar 24'.

The guides 20 have extending forwardly from the upper ends thereof upper horizontalguides 25, the purpose for which will be hereinafter described. A cradle generally designated as 26 is disposed in theframe structure l5 and comprises a U-shaped member which is open at each end. The cradle 26 is formed of U-shape'd end members 2! connected together by lower connecting bars 28, and upper connecting bars 29 and 30.

A guide rail 3! is connected between the uprights 32 at the front of the cradle 26 so as to prevent the lower portion of the basket 33 from slipping downwardly and outwardly from the cradle at the time the latter is tilted to discharge the bobbins disposed in the basket 33.'

The frame l5 has mounted adjacent each end thereof rollers 34 over which the runners 35 at the bottom of the basket 33 are adapted to movably engage. The cradle 26 is also provided with transversely extending rollers 36 which are in substantially the same plane as the rollers 34 so that the basket 33 can be readily moved onto the cradle when the basket is in a filled position.

The basket 33 is adapted to be locked atits rear portion by means of L-sha-ped locking members 31 which are secured to a shaft 38 rotatably carried by the upper rear portion of the cradle 26. 'The locking members 31 are engageable over the rim of the basket 33 at'the rear thereof, and the locking members 31 are fixed in locked position by means of a locking bar 39 pivotally mounted on a pivot 40 carried by one end of the cradle 26.- When the locking member 39 is swung in a clockwise direction, as viewed in Figure 5, this locking member will overlie an adjacent basket looking or clamping member 37.

The cradle 26 has secured to the front uprights 4! thereof upper rollers 42 which engage in the guide members 20, and each upright 4| has secured thereto a lower roller 43 engageable in a guide channel 20 and movable out of the channel 2B through an opening 44. When the upper roller 42 is moved forwardly by means of a curved guide 45 positioned at the upper end of the upright channel 20 and is then moved forwardly into the horizontal channel 25, the roller 43 will swing rearwardly and upwardly through the opening44.

The cradle 26 istilted from. anupright recured at. their lower ends, as at 41, to the cradle.

26 and are wound about a pair of winding drums 48 mounted on the winding shaft 49. The shaft 49 is journalled in bearings 56 carried by the top frame bars 22, and the shaft 69 at one end thereof has secured thereto a sprocket 5l about which a chain 52 engages. The chain 52,ex tends downwardly and rearwardly and is trained about a lower small sprocket 53 whichis secured-to -a crankshaft 54. A crank 55 is carried -by.the crankshaft 54 and is disposed outwardly of a housing or shield 56 engaging about the chain 52.

Theshaft lii has secured thereto a'ratchet wheel "51 with which a spring-pressed pawl"'58 engages, the pawl 58 being rockably carried by a pivot 59 which engages through an ear 66 carried bythe adjacent upper frame bar 22. The pawl'58 is constantly urged to'latching' position by means of a spring 6|.

In order to provide a means whereby the Qcradle26 will not be permitted to drop downward when in a tilted or discharging position; by, rearward'movement of the rollers 42 in the horizontal channels '25, I have provided locking rollers wardly at its forward side until the cradle is in an upright position.'

I do not mean to confine myself to the exact details of construction-herein disclosed, but claim all variations falling within the purview of the appended claims.

What I claim is:

wheeled carrier for bobbins comprising a mobile frame, a basket cradle of U-shape in said "frame,"a pair of confronting channel shaped veriticalaguidesatthe forward 'side of said frame, a

"when said-cradle is in-a lower1receiving position,

' an intermediate rollercar'ried bysaid cradle be- 'or;pins'62which are carried by the uprights 4! and are movable in the chanels 2t and25.

'Inthe use and operation of this device, the basket 33 .is initially filled with bobbins which areto be discharged into'a receiving bin'B. The basket 33 is rolled into the cradle 26 and locked therein by the locking members 3?. The frame .[5 is then moved to the'front of the bin B and the cradle 26 may be raised to a tilted'discharging position vby turning the crank 55. The cables 43 will raise the cradle 26, the lower rollers 43 ini 'tiallypreventing'the tilting of the cradle until .the upper rollers 42 pass into the rear ends of the horizontal channels 25.- When the upper rollers42 are in the rear ends of the upper channels 25, the lower rollers 43will be in alignment with the openings 44 of the upright channelslfl sothat thefurther-winding of the winding shaft id will cause the cradle. 26 to tilt upwardly at .its rear side. 'The cradle 26 may be tilted to the desireddegree which maybe either in a horizontal position slightly above orbelow the horizontal, depending upon the number of bobbins which are to be discharged into the binB.

When the cradle. 26 is tobe lowered, the pawl member 58-. is released from the ratchet'57. and the crank 55 is rotated inan unwinding direction. When'the rear end of cradle ZBswings downwardly with upper rollers 62 as fulcrums, intermediate rollers62 will swing downwardly into channels ZU and willstrike the front-walls. of channels (29 forming intermediatefulcrums for *front bars 24 so that atthe time3rollersl3 are entering-openings id-rollers will be moving rearwardly in horizontal channels 125. When rollers-43 are entirely within channels 20 the front bars 24 of cradle-26 'willbe very close to vertical and-rollers? will be atithe inner .ends of upper channels 25 so that rollers-@2- may readilyrenter'. the upperq-endsof 'cha-nnels'iil. At. this time the rollersl42 will beentering: the upper end oft-he channels 20 so that further unwinding of the shaft ts will permitthe :cradle-to drop 'ver- 25 and the locking members 62 thelcarrier'or cradle! 6 will' be prevented? from dropping downtween said pair of rollers engaging in saidvertical "guides for holding-said cradle against rear-ward -movement-when said cradle is in a-tilted position and for effecting rearwardmovement of the upper' oneof said pair of rollers when said cra'clle 'is swung downwardly from a tilted toa vertical pair ofrollers may pass out of-'the 'vertical guide at the time the upper one of saidrollers is-entering the" horizontal"extension to thereby provide for tilting of said cradle.

2. 'A wheeled carrier for bobbins comprisinga mobile frame, a basket cradle of U-shape in said frame, a pair of'vertical guides at-the forward side of said frame;a-horizontalforwardly extending guide extension at the 'upperen'dof-each-vertical'guide, a roller carried by each end of-said cradle engaging saidvertical guide when said cradle is in a lower receiving-position and engaging in said guide extension when said cradle is in an upper tilted positionymezins for looking a basket in saidcradle, a lower roller carried-by each end of said cradle engaging in said vertical guide, an intermediate roller carried by each end of said cradle 'engaginginsaid vertical guide, each guide having an opening in the inner-side thereof abovethe lower-end thereof, and" means engaging the lower rear portion of'said cradle for tiltingthe latter said lower roller j-passing rearwardly through said'opening at the time said first named'roller is entering said horizontal-guide whereby saidcradle will ,be tilted by furtheril pward movement thereof, said'intermediate roller constituting means whereby during the "downward: movement of said cradle, said, first-named roller will be held against-rearward movement in said horizontal extension without "downward swinging of said cradleto an nprightposition.
